RAILWAYFROG.

SPECIFICATION forming part of Letters Patent N o. 639,251, datedDecember 19, 1899. Application iile July 22, 1899. Serial No. 724,852.(No model.)

To all whom t may concern:

Be it known that I, CARL F. KREss, J r., of Johnstown, in the county ofCambria and State of Pennsylvania, have invented a new and usefulImprovement in Railway-Frogs,

of which the following is a full, clear, and eX- act description,reference being had to the accompanying drawings, which form a part ofthis specification.

My invention relates that class of frogs which are built up of rails orrail-sections properly fitted together and connected by a solid chuckcast between them and through apertures in their web portions.

The objects of my invention are to provide a frog of the class describedwhich shall be light and durable and built up of a minimum Iof partscapable of being readily constructed, fitted, and secured together, andwhich by its center construction provides for an increased width ofwheel-bearing.

To these ends my invention consists in the novel construction,arrangement, and combination of parts hereinafter described, and pointedout in the appended claims.

Referring to the accompanying drawings, Figure l is a plan view of myimproved frog. Fig. 2 is a section on the line :t x of Fig. l, and Fig.3 is a section on the line y y of Fig. 1.

A and B designate two continuous T-wing rails bent as shown.

C is a guard-rail, and D is the cast chuck.

Cut in the head of the rail B are two wheelgrooves ff', whose edgesaline, respectively, with the inner lines of the head of the wingportions of the rail A and with the inner line of the head of theguard-rail C. These two grooves leave between them a triangular centeror apex portion d of the rail B,whose outer .straight face is planed andfitted to the inner planed face a of the central straight portionV ofthe rail A, the base-anges of the rail B fitting or overlapping theinner base-flangeof the rail A at the cent-er of the frog and overlappedupon tlie opposite side by the inner base-flange of the guard-rail C,which is bent to conform to the angle of the rail B, and has a broadenedcentral head portion c opposite the portion inthegrooveintersectionbeingformed in part in the head of the rail B and inpart in the head of the guard-rail, as seen in Fig.

2. The guard-rail has apertures c through its web portions, throughwhich extend the connecting portions of the cast chuck, which fills thespace between the webs of the several rails jand underlies and supportstheir heads, forming a solid floor for the frog. This chuck also extendsbetween the rails A and B to each side of the center of the frog topoints preferably about coincident with 6o the ends of the guard-rail,Hoor-plates F being provided to form the bottoms and guardwalls of thewheel-groove. These plates are fitted to the webs ofthe rails A, asshown in Fig. 3, and extend, respectively, from the groovesff to theends of the chuck D. They are formed with inclines or risers (indicatedat f2) for the purpose of raising the wheeliianges in passing over thefrog. Similar inclines or rising surfaces f3 are provided in the 7owheel-grooves of the guard-rail. The several rails, together with theHoor-plates, are further united by bolts I-I, which extend through therails and through holes cored in the chuckcasting.

It will be readily seen that the construction described reduces toaminimum the number of parts and provides a rigid and durable structure.

The formation of the rails A and B at their 8o central portions with thetriangular-head portion b abutting the head of the rail`A provides, itwill be seen, a considerably-increased width of wheel-bearin g and makesa neat frog center construction. 4 8 5 I do not desire to limit myselfto the exact construction which I have described, as the same may bevaried in detail without departing from the spirit and scope of myinvention.

Having thus described myinvention, what 9o I claim, and desire toprotect by Letters Patent, is-

1. The herein-described railway-frog composed of the two wing-railshaving each a straight intermediate portion abutting a similar portionof the other rail, one of said rails having both wheel-grooves formedacross its head, a guard-rail bent to conform to the grooved wing-rail,and having head-grooves which aline with the grooves in the wing-rail,roo and means for securing said rails together'.

2. The herein-described railway-frog cornposed of two wing rails havingabutted straight portionsintermediate their wings,one of said railshaving both Wheel-grooves formed aorossits head, a bent guard-railhaving headgrooves which aline with respective grooves at the wing-rail,a east-metal chuck, and movable bolts extending through the said railsand ohuek.

3. A railway-frog composed of two wingrails, having eaoh a straightportion intermediate its two Wings, one of said rails having` bothWheel-grooves formed in its head and interseoting across its straightcentral portion, the latter having the head portion intermediate saidgrooves formed with a straight faee which abuts the similar face of theintermediate portion of the other rail, the bent guardrail, the eastchuck filling the spaces between the wing and guard rails and castthrough the perforations of one of the Wing-rails, and the boltsextending througlrthe rail-webs and east chuck.

4. The herein-described railway-frog cornprising the bent wing-rails Aand B, having laterally-abutted intermediate portions, one of which hasboth Wheel-grooves of the frog out across its head, the bent guard-rail,the east ehnek, and the floor-plates between said ohnek and the rail A.

5. The herein-described railway-frog oomprising the laterally-abuttedmain rails, one of which has both the Wheel-grooves intersecting acrossthe head, the bent guard-rail having` the risers, the intermediate eastchuck, and the door and guard plates intermediate the ohuel; and thewing portions of the main rail on the opposite side from the guard-rail.

In testimony whereof I have affixed my signature in presence of twoWitnesses.
